Plotly Express add Attribute After Figure Creation

Say for example I have generated a plot using Plotly Express like so:
fig=, x=x_axis, y=y_axis, title=this_title)

How would I add a Plotly Express attribute after this figures creation? For example, I would like to be able to add points=all, and it seems something like .update_traces only operates on the lower-level go.Box() which the attribute ‘points’ isn’t an existent for.

In other words, how can I update the figure generated by Express (preferably using Express syntax but if I need to diverge from that that is ok). Thanks!
